We divide 52043703 by 66
The aim is to understand the frequency of 66 in 52043703.

Going ahead to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 66

Step 2:
When dividing 52 by 66, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 66

Going ahead to step 3:
When dividing 520 by 66, we get 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 462 from 520 leaves us with 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 66

Step 4:
The number 66 fits into 584 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 528 from 584 leaves us with 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 66

Let's proceed to step 5:
66 goes into 563 8 times with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 788.0
The remainder is 35 after subtracting 528 from 563.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 66

Advancing to step 6:
If we divide 357 by 66, we get 5 and a remainder of 27.
The next digit of our result is 5. 
Result so far: 7885.0
If we subtract 330 from 357, we get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 66

On to step 7:
If we divide 270 by 66, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 78854.0
If we take 264 away from 270, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 66

Advancing to step 8:
When dividing 63 by 66, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 788540.0
Subtract 0 from 63 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
When dividing 630 by 66, we get 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 788540.9
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 788540.95
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 66 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 788540.954
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 788540.9545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 788540.95454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 66 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 788540.954545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 788540.9545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 16:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 788540.95454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 788540.95454545, with a leftover of 3e-08.
